down converter

Down converter is a part to convert RF signal down to IF or baseband. Bascally, mixer part for frequency downward is called down converter. Abstract Using AlGaAs/GaAs HEMT technology, we designed, fabricated, evaluated a V- band monolithic downconverter . The downconverter consists of a four-stage RF amplifier and an image-rejection active-drain HEMT mixer. The HEMTs in the downconverter have
